Today I tried turning it on from the web interface and play some music. Nothing came out. I started investigating.

Basically what I have is the player seems to be working. It's seen by the server, it's seen by the router (it gets connectivity through WiFi and gets assigned an IP). If I sync player with it and start playing from it, the other players play music.

But the screen stays off and no sound comes out of it.

I think I tried correctly the Xiling thing but the screen didn't turn on at all.

Optical connection shows the usual faint red light.

Maybe your PSU is getting weak. That's the #1 issue I think, with #2 being a fried wireless card.
You need a 5V, 2A PSU.
I think I have read elsewhere the Touch PSU is compatible. Please check this fact before taking action, I would hate to be the cause of the destruction of an SB3 :)

Yup, found out as much. Came here to report back. Basically the AC adapter wasn't keeping the device on correctly. It's strange because I measured it later with a voltmeter and it outputs rock solid 5.12 Volts... but I haven't checked amperage, maybe that's where the problem lies.

Luckily I had a brand new AC adapter from a spare SB 2 that I'm keeping in my stash and with that it works a charm.

Now I'll try to score a couple of extra AC adapters, since they seem to be one of the weakest links in the chain.

Thanks for your help, epoch1970.

Same problem, same symptoms (player seen by router, voltage Ok on Vm), same solution (new charger).
Thanks !

But a voltmeter draws no current , to really measure you must open the case and measure the voltage while the power supply is connected to the SB . The voltage while loaded is the most interesting one .
